feathers ?.. Wait.. are you saying ? .. Your Iphone 4 is currently locked and that you wish to unlock it to use on digicel's network with all features and apps ?
whether its locked or not , apps and features isn't the issue unless you want to use the hotspot features this is dependant on carriers which both don't support currently.
But then again since its locked your gonna probably jailbreak it for the baseband to use it on other networks and you can gain use the hotspot feature.
theres also those sim tools like gevey and etc .. to get it to work on other networks .
